Celadon Jadeite Jade from Guatemala

  • 摘要: 通过对危地马拉灰绿色翡翠样品进行常规宝石学测试、岩矿鉴定、X射线荧光光谱、X射线粉末衍射及红外光谱等分析, 确定了其化学成分与硬玉的基本相同, 其矿物组成以硬玉为主, 含有少量的钠长石、白云母、钠云母及微量的黝帘石、金云母、榍石与方沸石等;主要为柱状、粒状变晶结构与粗粒变晶结构;红外光谱在1 000~1 100 cm-1范围内由于Ca, Mg等杂质元素替代Al引起vas (Si—O—Si) 反对称伸缩振动致1 071 cm-1处峰, 与缅甸翡翠的相比有明显漂移。
    Abstract: A celadon jadeite jade sample from Guatemala is studied by using the conventional gemmological methods, rock-mine identify, XRF, XRD and IR.The results show that the chemical compositions of the sample are similar to that of jadeite.The main mineral component is jadeite, including a few albite, muscovite, paragonite and a small amount of zoisite, phlogopite, sphene and analcime.The structure of the sample is mainly column-like crystalloblastic, granoblastic and coarse granoblastic textures.At the range of 1 000~1 100 cm-1, the result of Al replaced by Ca and Mg with other impurity elements leads to the infrared spectrum at 1 071 cm-1 caused by the antisymmetric stretch vibration of vas (Si-O-Si), which has the obvious drift when compared with that of the jadeite jade from Myanmar.
